Description

Technical Field

[0001] The invention relates to an adjustable uniform heating device, in particular to an adjustable uniform heating device for tire vulcanization nitrogen circulation. Background Art

[0002] The main advantages of using nitrogen vulcanization are energy saving and extending the life of the bladder. It can save 80% of steam and extend the life of the bladder by 1 time. Tires consume a lot of heat and electricity during the vulcanization process, so it is of great significance to develop and promote energy-saving vulcanization technology. Since nitrogen has a small molecular weight and heat capacity, when nitrogen is filled into the inner cavity of the tire bladder, it will not absorb heat and cause the temperature to drop, nor will it easily cause oxidation and cracking of the bladder.

[0003] When using nitrogen vulcanization, the nitrogen needs to be heated to the temperature required for vulcanization first, and then the nitrogen is connected to the vulcanizer for vulcanization. However, when the nitrogen is heated, due to the excessively fast flow rate of the nitrogen, when the nitrogen is discharged through the heating pipe, the heating time may be insufficient, resulting in the nitrogen temperature not being able to reach the temperature required for vulcanization, thereby affecting the vulcanization of the tire by the vulcanizer.

[0004] Therefore, it is necessary to invent a tire vulcanization nitrogen circulation adjustable uniform heating device that can adjust the flow rate of nitrogen, control the heating time of nitrogen in the heating pipe, easily reach the temperature required for vulcanization, and improve the nitrogen heating efficiency. Summary of the invention

[0005] In order to overcome the disadvantage that when heating nitrogen, due to the excessively fast flow rate of nitrogen, the nitrogen temperature may not reach the required temperature for vulcanization due to insufficient heating time when the nitrogen is discharged through the heating pipe, thereby affecting the vulcanization of the tire by the vulcanizer, the technical problem of the present invention is to provide a tire vulcanization nitrogen circulation adjustable uniform heating device which can adjust the flow rate of nitrogen, control the heating time of nitrogen in the heating pipe, easily reach the required temperature for vulcanization, and improve the heating efficiency of nitrogen.

A gas volume regulating device 7 is installed on the left side of the uniform heating device 6, and the gas volume regulating device 7 is used to adjust the amount of nitrogen discharged.

[0043] The uniform heating device 6 includes a spiral hollow ventilation pipe 61, a toggle frame 62, an air inlet pipe 63, an exhaust pipe 64, an oil filling pipe 65 and a pressure relief valve 66, see Figure 3 and Figure 4 As shown, a spiral hollow ventilation pipe 61 is rotatably installed in the heating cylinder 3, and the spiral hollow ventilation pipe 61 passes through the left and right parts of the heating cylinder 3. The spiral hollow ventilation pipe 61 can provide nitrogen circulation. The left end of the spiral hollow ventilation pipe 61 is fixedly connected with a toggle frame 62, and the toggle frame 62 is located on the left side of the heating cylinder 3. By rotating the toggle frame 62, the spiral hollow ventilation pipe 61 can be rotated. The right end of the spiral hollow ventilation pipe 61 is connected with an intake pipe 63. The intake pipe 63 It is connected to the air outlet pipe of the vulcanizer, the air inlet pipe 63 passes through the upper part of the bracket 4, the lower part of the air inlet pipe 63 is set as a spherical protrusion, the left part of the spiral hollow ventilation pipe 61 is connected with the exhaust pipe 64, the exhaust pipe 64 is connected to the air inlet pipe of the vulcanizer, the exhaust pipe 64 passes through the upper part of the bracket 4, the left part of the heating cylinder 3 is connected with the oil filling pipe 65, the oil filling pipe 65 passes through the upper part of the bracket 4, the right part of the heating cylinder 3 is installed with a pressure relief valve 66, and the pressure relief valve 66 passes through the upper part of the bracket 4.

[0044] The gas volume regulating device 7 includes a hollow column box 71, a first rotating shaft 72, an arc hole column block 73 and a handle 74, see Figure 6 and Figure 7 As shown, a hollow column box 71 is embedded in the middle of the exhaust pipe 64, and a first rotating shaft 72 is rotatably installed at the center of the hollow column box 71. The first rotating shaft 72 passes through the upper and lower parts of the hollow column box 71, and an arc hole column block 73 is installed in the middle of the first rotating shaft 72 by a key connection. The arc hole column block 73 is located in the hollow column box 71, and a handle 74 is fixed to the lower end of the first rotating shaft 72. The handle 74 is located at the lower part of the hollow column box 71. By turning the handle 74 to drive the first rotating shaft 72 to rotate, the arc hole column block 73 can be driven to rotate.

[0045] First, the operator fills the heating cylinder 3 with heat transfer oil through the oil filling pipe 65, and then energizes the heating rod 5 to preheat the heat transfer oil in the heating cylinder 3 through the heating rod 5. Then, the nitrogen in the vulcanizer is discharged into the air inlet pipe 63, and the nitrogen in the air inlet pipe 63 is discharged into the spiral hollow ventilation pipe 61. At this time, the operator rotates the toggle frame 62, and the rotation of the toggle frame 62 drives the spiral hollow ventilation pipe 61 to rotate. The rotation of the spiral hollow ventilation pipe 61 can make The nitrogen in the spiral hollow vent pipe 61 is heated evenly. When the nitrogen is heated in the spiral hollow vent pipe 61, the handle 74 is turned forward. The forward rotation of the handle 74 drives the first rotating shaft 72 and the arc hole column block 73 to rotate forward. The forward rotation of the arc hole column block 73 blocks the exhaust pipe 64, so that the nitrogen flow rate discharged from the spiral hollow vent pipe 61 to the vulcanizer through the exhaust pipe 64 can be reduced, so that the nitrogen stays in the spiral hollow vent pipe 61 for a longer time, and the heating time of the nitrogen is extended, so that the nitrogen can be improved. The heating temperature, when the nitrogen is heated to a sufficient temperature, the handle 74 is reversed, and the reverse handle 74 drives the arc hole column block 73 to reverse until the arc hole column block 73 no longer blocks the exhaust pipe 64. At this time, the nitrogen flow rate discharged from the spiral hollow vent pipe 61 to the vulcanizer through the exhaust pipe 64 can be increased, and the tire can be vulcanized. The nitrogen will cool down after entering the vulcanizer for use, and then it will be discharged from the vulcanizer into the intake pipe 63 again. When the heat transfer oil in the heating cylinder 3 is continuously heated, resulting in excessive air pressure in the heating cylinder 3, the heating cylinder 3 can be depressurized through the pressure relief valve 66 to maintain a constant pressure in the heating cylinder 3. When the tire is vulcanized, the operator stops rotating the toggle frame 62, and the spiral hollow vent pipe 61 stops rotating. The operator then disconnects the power supply of the heating rod 5 to prevent the nitrogen from being discharged into the intake pipe 63. In this way, the nitrogen can be evenly heated, thereby improving the efficiency of nitrogen heating. The heat transfer oil is heated by energizing the heating rod 5, and the spiral hollow ventilation pipe 61 is heated by the heat transfer oil. Then, nitrogen is connected to the spiral hollow ventilation pipe 61, and the spiral hollow ventilation pipe 61 is driven to rotate by rotating the toggle frame 62 to evenly heat the nitrogen. The operator holds the handle 74 to drive the first rotating shaft 72 and the arc hole column block 73 to rotate forward and reversely, so as to adjust the discharge speed of the nitrogen and control the heating time of the nitrogen. In this way, the nitrogen can be evenly heated, thereby improving the efficiency of heating the nitrogen.

[0046] The device also includes an intuitive adjustment device 8, which includes a second rotating shaft 81, a bevel gear assembly 82, an eccentric hole column 83 and a driving disk 84. Figure 8-Figure 12As shown, a second rotating shaft 81 is rotatably installed on the left part of the bracket 4, and the second rotating shaft 81 passes through the bracket 4. A bevel gear assembly 82 is connected between the second rotating shaft 81 and the first rotating shaft 72. By rotating the second rotating shaft 81, the first rotating shaft 72 can be driven to rotate through the bevel gear assembly 82. An eccentric hole column 83 is installed on the upper left part of the bracket 4 by bolts. The second rotating shaft 81 passes through the eccentric hole column 83. A driving disk 84 is rotatably installed on the left part of the eccentric hole column 83. The right side center of the driving disk 84 is fixedly connected to the second rotating shaft 81, and an arc-shaped through groove 85 is opened at the lower part of the driving disk 84. By observing the positions of the driving disk 84 and the eccentric hole column 83, the position of the arc hole column block 73 in the hollow column box 71 can be observed.

[0047] The drive device 9 includes a driving impeller 91, a planetary gear assembly 92, an input shaft 93, a reduction output shaft 94, a small column gear 95 and a large column gear 96. Figure 13-Figure 16 As shown, a driving impeller 91 is rotatably installed in the spherical protrusion at the lower part of the intake pipe 63, and the left part of the driving impeller 91 passes through the spherical protrusion at the lower part of the intake pipe 63. A planetary gear assembly 92 is installed at the lower part of the intake pipe 63 by bolts, and an input shaft 93 is installed at the right part of the planetary gear assembly 92. The right end of the input shaft 93 is connected to the left part of the driving impeller 91 by a shaft coupling, and a reduction output shaft 94 is installed at the left part of the planetary gear assembly 92 by a key connection. A small column gear 95 is installed at the left end of the reduction output shaft 94 by a key connection. By rotating the input shaft 93, the reduction output shaft 94 can be driven to rotate slowly through the planetary gear assembly 92. A large column gear 96 is installed at the right end of the spiral hollow ventilation pipe 61 by a key connection. The large column gear 96 is located on the right side of the heating cylinder 3, and the large column gear 96 is meshed with the small column gear 95. By rotating the small column gear 95, the large column gear 96 and the spiral hollow ventilation pipe 61 can be driven to rotate.

[0048] The operator holds the driving disk 84 and rotates the driving disk 84 and the second rotating shaft 81 forward and reversely. The forward and reverse rotation of the second rotating shaft 81 can drive the first rotating shaft 72 forward and reversely through the bevel gear assembly 82. Then, by observing the position of the hole on the eccentric hole column 83 and the arc-shaped through groove 85, the position of the arc hole column block 73 in the hollow column box 71 can be observed. When the hole on the eccentric hole column 83 corresponds to the middle of the arc-shaped through groove 85, the nitrogen flow rate discharged from the exhaust pipe 64 to the vulcanizer is adjusted to the maximum. In this way, the position of the arc hole column block 73 in the hollow column box 71 can be observed, thereby accurately adjusting the flow rate of the nitrogen in the exhaust pipe 64. By rotating the driving disk 84, the driving disk 84 drives the second rotating shaft 81 to rotate, and the second rotating shaft 81 drives the first rotating shaft 72 and the arc hole column block 73 to rotate through the bevel gear assembly 82. By observing the positions of the holes and the arc grooves 85 on the eccentric hole column 83, the position of the arc hole column block 73 in the hollow column box 71 can be observed, thereby accurately adjusting the flow rate of nitrogen in the exhaust pipe 64.

[0049] When nitrogen flows in the intake pipe 63, when it is discharged through the spherical protrusion of the intake pipe 63, the flow of nitrogen will drive the driving impeller 91 to rotate, and the rotation of the driving impeller 91 will drive the input shaft 93 to rotate, and the rotation of the input shaft 93 will drive the reduction output shaft 94 to rotate slowly through the planetary gear assembly 92, and the slow rotation of the reduction output shaft 94 will drive the large column gear 96 to rotate through the small column gear 95, and the rotation of the large column gear 96 will drive the spiral hollow ventilation pipe 61 to rotate, and the torque is initially increased by the planetary gear assembly 92, and then the small column gear 95 drives the large column gear 96 to rotate to increase the torque for the second time, so as to avoid the inability to drive the driving impeller 91 to rotate when the nitrogen flows. In this way, the spiral hollow ventilation pipe 61 can be automatically driven to rotate when the nitrogen is discharged through the intake pipe 63, so that the operator does not need to manually rotate the spiral hollow ventilation pipe 61 by turning the frame 62. The flow of nitrogen drives the driving impeller 91 to rotate, and the rotation of the driving impeller 91 drives the input shaft 93 to rotate. The rotation of the input shaft 93 drives the reduction output shaft 94 to rotate slowly through the planetary gear assembly 92. The slow rotation of the reduction output shaft 94 drives the large column gear 96 to rotate through the small column gear 95. The rotation of the large column gear 96 drives the spiral hollow ventilation pipe 61 to rotate. In this way, when the nitrogen is discharged through the intake pipe 63, the spiral hollow ventilation pipe 61 can be automatically driven to rotate, thereby eliminating the need for the operator to manually rotate the spiral hollow ventilation pipe 61 by turning the frame 62.

[0050] Also includes a positioning pin rod 10 and a spring 11, see Figure 17-Figure 18 As shown, a positioning pin rod 10 is slidably installed on the left part of the exhaust pipe 64 , a spring 11 is connected between the positioning pin rod 10 and the exhaust pipe 64 , five positioning holes 12 are opened on the upper part of the first rotating shaft 72 , and the positioning pin rod 10 cooperates with the positioning holes 12 .

[0051] Also includes a protective cover 13, see Figure 19-20 As shown, a protective cover 13 is installed on the right side of the heating cylinder 3 by bolts, and the protective cover 13 covers the driving device 9.

[0052] It also includes a fixing ring 14 and a spiral blade 15, see Fig. 20 As shown, the left and right parts of the spiral hollow ventilation pipe 61 are both fixedly connected with fixing rings 14 , and a spiral blade 15 is fixedly connected between the two fixing rings 14 .

[0053] By inserting the positioning pin 10 into the positioning hole 12, when the first rotating shaft 72 rotates, the positioning pin 10 first moves backward, and the spring 11 is compressed accordingly. Then, when the positioning hole 12 corresponds to the first rotating shaft 72, under the action of the spring 11, the positioning pin 10 moves to the left and is re-inserted into the positioning hole 12. Through the cooperation between the positioning pin 10 and the positioning hole 12, the first rotating shaft 72 can be positioned.

[0054] By heating the protective cover 13 on the right side of the cylinder 3, foreign objects can be prevented from being drawn into the driving device 9, thereby avoiding the danger of foreign objects being drawn in. At the same time, the protective cover 13 can protect the driving device 9 inside to avoid damage to the driving device 9 due to bumps.

[0055] When the spiral hollow ventilation pipe 61 rotates, it drives the fixed ring 14 and the spiral blades 15 to rotate. The spiral blades 15 stir the heat transfer oil in the heating cylinder 3, so that when the heating rod 5 is heated, the heat transfer oil in the heating cylinder 3 is heated more evenly.
